TO ALL'WHOM IT MY CONRN:

Be it knownthat-I, Rnrns DU'rroN, ofthe city of New York, inthe county of New York, and State of New York, haveinvented certain new and vuseful Improvements in the Construction' of the Frames of Harvesting Machines, and the parts immediately connected therewith and I do hereby declaro that the following is a full, clear, and exact description thereof, and of their mode or manner of operation, referenceheing had to the accompanyng drawings, and to the letters of reference marked thereon, and making a part of this specification.

My improvements have relation to an improved construction and arrangement ofthe frames of harvestingmachines, and of the parts immediatelyvconnccted therewith, by which the whole machine is rendered lighter, more compact, less likely to get out of order, and more durable, and better adapted to the uses to which it is to be applied.

Figure 1 is a general plan view of the frame of a harvester, showing the relative positions of the several parts, and representing some parts in section.

Figure 2 is a representation of the conpling-piece, which connects the front end and the inner sidesof the fra-me, and to which also the finger-bar is attached. V

Figure 3 is a side view of' iig. 2. l

Figure 4 shows a different mode of connecting the pole to'the frame from that shown in g. 1`-

Figures 5 and 6 show the manneroof attaching the whiie-tree'lto the pole.`

Figures 7 and 8 show the mannerof attaching the dra'ught-hoolr to the frame.

Figure 9 shows the connection between the whiietree`end draught-hook.

Figure 10 is a sectional view of part of the crank-wheel fender.

A hollow sleeve, whichentirely covers the axle-treo between the two wheels, andthe ends of which form the axle-tree boxes, constitutes one end of th'emachine, and to the other end of themachine, when such sleeve is the back end-of the machine,`the draught is attached. i i i A casing, within which are enclosed tho bevel-gear and pinion, bevel-gear shaft, and crank-shaft, and the four journal-boxes for the same, formsthe left-hand side of the frame, and the right-hand side is s. strong wrought- Viron bar, which forms the connection between the inside shoe and the axle-tree. The casing, `which forms the left-hand side of the frame, is composed of two metallic pieces C c, fig. 1. A section' of this side of the frame, through the red line a is also shown, in which C C represents one of the metallic pieces of the. casing, and c c the other part or piece of such casing. l Q represents asection of the crank-shaft, enclosed within such casing, and ef shows the small open space 4between such shaft and the inner side of the casing, which space permits the-crank-shaft to turn freely without rubbing against the innerv surface of the easing," The psrts or pieces C C c c meet together, as seen at the red line a b, and at 1 1, the two. parts passing over and around the crank-shaft Q, and forming a. complete covering or protection for it, 2 2 representing `the open spaces between the two parts of euch casing. The endsnof the crank-shaft are turned of lucent size to form suit-v able journals or bearings, opposite which the space e" is filled with Babbit .or other suitable metal, `to furnish proper boxes for such shaft to turn in; or, if preferred, the casing inay be thickened, so 'as toili such space c" at the ends of the crank-shaft, and then bored out, so es to form the journal-boxes. The cssings 0 c, at

one'end, are also enlarged, and made of sufficient diameter to enclose and form a case for the bevel-gearing and-pinion, as shown by the red lines in fig. 1. Therlines 4 and 5 show the direction of the bevel-wheel` and crank-shaft, and the projections z z on the casing, `opposite each other, 'are made hollow, and lled-with Babbit Ofi-suitable metalto form the journal-boxes for the bevel-wheel shaft d. 4 Such casingis made suiciently tight, so that dust is excluded from nearly all the'fast-running parte Vof the machine; and, asthe journaflfboxes are formed within this easing, the shafts and gearing cannot he thrown outof line by the warping or `twisting of the frame. The keepingvof the shafts and gearing inwline is indispensable. 5 w k "Near the inner end of. the bevelwheel 'shaft d is turned a groove, d', iig. 1, in'whlch rests a 'forked plOjeC tionof the shifter-lever n. One end of such lever is'pivotedat n to a projecting piece, of the casing; lm

. thevother end rests in an elongated mortise, 3, on the axle-sleeve D, and on the upper eide of such l mortise is a projection, o, against which the'edge of such lever rests and presses. yThe upper endof such lever-is date tened, es shown st n",lto form n. suitahlevsurface-for operating such lever with the foot. By shifting auch lever intothe space o', the bevel-wheel shaft d is moved in the direction of the arrow by the action of the forked projection of such lever in the groove d', and the bevel-gear is thrown out of gear with the bevel-pinion. A reverse movement of such lever throws the parts in gear again. ',lo the under sidemf such lei'ver n is fixed a spring, the' upper end of which bears on the sleeve, under the mortise 3, keeping the lever against it, the-projection o holding the lever when shifted, so as to throw the parts in or out of gear. I i

To the outer 'end of the bevel-wheel shaft d is keyed or fastened the spul-pinion l, which is worked by the spur-gear L A section of a fender for enclosing and protecting the spur-pinion l is shown at m. Such fender is castlwith a hole suiiiciently large to pass over the end of the projection on the casing C, and is held i n place by the small bolt or screw m.

C e are projections upon the casings C c, threugh-` which the axle-sleeve D passes, and on such sleeve is a projection; D', against and to which 4the casing projections C c' are bolted by bolts'a' a', such bolts holding the cssings firmly and rigidly to the sleeve, and .also fastening the casings together. The forward` ends of the casings' are bolted firmly to the flange on the front end, E,'oi` the frame', by the bolts c le. The front end, E, of Ythe frame, is made of round rod or bar-iron, one and a quarter to one and a half inch in diameter, tho ends of which are turned, so os to allow thefclamp-piece e andthe coupling-piece G to he firmly fastened thereto, `auch pieces e G-being also used for `fastening the front end of the frame to the sides C and-F. Such clamp piece or flange e is fastened to the casing by two bolts, one'of whichV is' 'shown at e' c'; the same bolts also fastening the two casings together, and likewise securing the back! plate 1t of the crank-fender to the end of the casings. Such bolts thus serve several purposes, fastening the front end of the frame to the side casings, fastening the different parts of the casings together, and securing the crank-fender to the casing.

The V'side F of the frame is made of a single har of iron, bent in a suitable shapeto connect witll'the coupling" pice G on its under side, and sustainjsuch piece at a. proper height for supporting the nger-bar. An edge view of such bar F is shown in iig. 2, and a sectional view in iig. 3. To the end of such bar is fastened, by a bolt,f, o hooked shield, f,I for preventing the grass from falling upon tho shoe, and thus clogging the knife.

The front end, E, of ythe frame p asscs through a hole in the coupling-piece G, as shown at E', fig. 2. This hole splaced above the bar F, thus elevating the front end o f the frame high enough to pass v'cr obstructions. Such couplingpiecc Grisv also provided with a curved slot, G', the centre of which is at zr, and below such slot are recesses l' 2 3, which slot and recesses are'm'ade use of in elevating the points of the ngerguards.

The sleeve D oncases the axle-tree M, between the hubs of the wheels A and'B. The ends cffsuch sleeve A are nished or constructed so as to form bearings for the axle-tree .to turn in, while the opening in the body of the sleeveis enlarged, so that the axle will turn in it without rubbing. Such sleeve thus forms both a casing 'and a support tothe axle,'l.nd as the bearingsare at-the ends of the' sleeve, the weight of the machine is supported on the axle, close to the hubs. A sectional view of the axle is shown at'M, g.

The pole is connected to the machine by being bolted to a coupling-clamp, H, which is fastened so as to turn freely upon the axle-tree sleeve D. Such clamp H is so fastened to such-slseve bynneans' oftwo clasps4 or clips, an edgeview of which is shown at D', iig. 4, whichpass around the sleeve, and the' ends of which pass through the clampV H, as seen at r r-r r, iig.'1, and r r, iig.- 4, and on which are threads to take nuts. to hold such clasp to the clnmp. By such arrangement tho pole is attached to the sleeve, directly over the'axle of the`machine, and lthus both the pole and frame -turn on s common axis. The pole isalso free to work up and down, independently of the frame. To this same clamp-piece H are also fastened lthe foot-board and the seat for the driver. Such seat thus has its bearing directly over or upon the axle, and is controlled by and moves'with the pole. l l l Fig. 4 shows another method of attaching the pole to the machine, which may be made use ox when-it is desirable that the weight of the driver should be employed in balancing or 'rendering lighter the front end of the machine. M is asection of the axle, and D of the sleeve around it, having ears or projections, 4 4, cast upon it, upon which'is .placedthe coupling-clamp H, and around which may pass the clasps, as beforedescribed.

By bolting the couplingclomp H so that it will turn on such eax-sor projections, the weight of the driver is that by so placing the weightof the driver on one side of the-axle, as described, it `wlll`teud tobalauce the other end of the frame.v

The crank-wheel fender is formed of two metallic pieces, U and T, connecting together by a hinge, `#and which, when closed, entirely cover and protect the crank-wheel, except at the end toward-the hoger-bar, and for a space suilicient'for the working of the connecting-rod. The front part, T, of such' fender is fastened or held,

when shut upon .the rear or back Aplate U, by means of a ea'teh, it', and 'sprin-g`, `t, which are 'shown more' clearlyin section in iig. 10.`` By lso hinging'the partTthe operator cancasily open the fen'der, as 'shownat T'-,

to cil or iix Athe bearing, g, of the connecting-rod, and when the`.connecting-rod is placed on thecranbpin g,"'and".

the plate T closed'and ,xastened by its catch andlspring, such connectinge'rodwill he held in place on the crapkpin without the aid of any bolt or pin, as heretofore required. It is important that not only thesundcr but the upper side of the crank-wheel should be protected, as when this is notdone the long grass is liable to get wound aboutit, andinterfere with the working of the machine. The fender described forms a complete covering'and protection for the cranlbwheel 'and the upper end of the connecting-rod 'against grass and other obstructions.' As' before stated, the back part of the .fender is secured'to the casing by the same bolts that hold the two parts of thecasing together, andwhich fasten the front end ofthe frameto s'uch casing.

Y Figs. 5 and '6 show a device for holding the whiiIie-tree. to the under side of the pole. K is a'section'al view oi' the pole, and W' is a sectional view of the whiiiie-tre'e. Y is the pole-iron, or an ironplate fastened to' the under side of the pole, and y shows an opening or recess therein, by,w hich is supported and in which moves the plate or part @"(ig. 6) of the whiiiietrce iron, to the ring or hook' yf" ofwhich is attachedthe'draughtaod placed orthrwny beyond theaxle and' on the side 'opposite the other end of,thc pole or frame.' 1t is apparent ym', (iig. 9.) In the front end of such poleiron Y is an opening, 2, (fig..6,) by means of which the part `1/ of the whiiile-tree iron can be put into and removed froml the recess y. By unhooking the lower end of the draught-rod ym', the whiie-t'ree can be detached, by slipping the part y out of tlie opening 2, without remov` ing any bolt or screw; and, on the other hand, Vwhen thewhiie-tree is to be attached, it is only necessary to slide such party into the opening 2, and hook the lower end'of the draught-rod tothe book P, (iig. 9.) .The

whiille-tree is thus not only held to the under side'of the pele, but can freely move forwardsnd backwards as the front end of the frame rises and falls. E, fig. 9, is a. sectional view of the front end of the frame, around `which passes the draught-hook, and to which it is fixed. I

Figs. 7, 8, and 9 also show-a manner of connecting the draught-hook' to the frame, so as to relieve the frame' and machine from sudden strain. E shows a section or part of the front end of the frame, and? the draughthook passing around it. Behind such part E, 'and between it and theextension of the draught-book, is placed V a coiled spring, p, supported by a pin or projection, p', extending backwards from the frame E, and through the back end of the hook P, as shown in the dra-wings. Als the draught is applied to the whille-tree W, the spring pf yields somewhat, and relieves the frameand machine from sudden strain, as in starting, or when the bar meets ,with resistance or obstruction. Such spring also renders the draught and action ofthe machine much leasier, and more uniform in passing over uneven ground,` and in overcoming the ordinary resistance to which it is subjected.

Through the shifterlever u., and opposite the 'inner end of the bevel-wheel shaft d, passes a screw, n", the

point of which presses against the end of such shaft. By turning such screw out orin, the cogs of the bevel-gear and spur-pinion are made to lit properly together. As the gear is liable to become changed, from being worn by use, it is desirable to have some method by which the operator can conveniently adjust such gear ,whenever required. This he can readily do by means of the screw-bolt n" operating on theendof the bevel-wheel shaft d.

Behind the axle-tree, and near the inner driving-wheel, is placed vthe raker's stand, for him to remove the grain fromthe platform when the machine is used as a reaper. Such stand is supported by the metallic piece R', (iig. 1,)'which is fastened' to the pole-clamp II by the clasps and their nuts r r. The board or platform R,

on which the raker stands, is placed about eight inches below the `top of thexle. S is a front piece for him to2; lean against while raking olf the grain, and 'is fastened to the top of the standard S', and S is a piece on which4 the rakercan rest when not at work, and which also steadios him in position, as bestands asti-ide of-it, and usos itl as a kind of saddle. Such position of the raker behind and below the axle is found most convenient to enable h im to easiest remove thegrain from'the platform. i.

What I claim as my invention, and desire tosecure by Letters Patent, is-
